Transcript Definition of Serious Injury

Dia Gainor, NASEMSO
National
EMS System Information
System (NEMSIS) Version 3.0
Compliant Out-of-Hospital
Records
Emergency Department
Discharge Databases
Hospital Discharge Databases
Trauma Registries
Physiological
scoring systems
 Glasgow
coma scale
 Trauma score
 Revised trauma score
 TRISS methodology
Anatomical
scoring systems
 Abbreviated
injury score
 Injury severity score
 ICD-9 Injury Severity Score
Calibrated
by the Association for the
Advancement of Automotive
Medicine
First developed in 1969
Anatomically based
Consensus derived
Updated every five years
Has been adopted by numerous
other countries

Extremity
External

ONLY
highest AIS number in
each body area is used
3 most severely injured body
region scores squared
3 squared scores added
together
= Injury Severity Score
If
injury is assigned a 6
(unsurvivable), ISS
automatically = 75
Score Reflective of Injury Severity
1 - 9 Minor
 10 - 15 Moderate
 16 - 24 Moderate/Severe
 ≥ 25 Severe/Critical

Many
different injury patterns yield
same ISS score
Errors of AIS scoring = errors of ISS
Injuries to different body regions are
not weighted
Limits the number of contributing
injuries to 3
Can’t account for multiple injuries
to the same body region
Anatomical
scoring system for
patients with multiple injuries
ISS score correlates with
mortality, morbidity & hospital
stay
Bivariate correlation of mortality
% with ISS and age
